Alcoholism, or alcohol use disorder (AUD), is a widely accepted disease model that characterises problem drinking as a chronic brain disorder with impaired control over alcohol consumption. The model suggests that alcoholism is caused by a combination of biological, psychological, and sociocultural factors, including genetic predispositions, environmental influences, and neurochemical deficiencies. Evidence supporting the disease model includes the identification of genetic influences on drinking behaviour, the presence of withdrawal symptoms and physical cravings, and the effectiveness of medical evaluations and treatments such as behavioural therapies, mutual-support groups, and medications. However, some critics argue that the disease model removes personal responsibility and increases the likelihood of relapse, while others emphasise the role of stigma and moral failing in the development of alcoholism.

What You'll Learn
Alcohol use disorder (AUD) is a disease of the brain
The modern disease theory of alcoholism states that problem drinking is caused by a disease of the brain, marked by altered brain structure and function. The largest association of physicians, the American Medical Association (AMA), declared that alcoholism was an illness in 1956. In 1991, the AMA further endorsed the dual classification of alcoholism by the International Classification of Diseases under both psychiatric and medical sections. Under the model of alcoholism, AUD is viewed as a chronic problem requiring abstinence.
The disease model of alcoholism is widely accepted today. It is seen as a useful perspective for understanding and treating addiction because it emphasizes the importance of medical treatment, therapy, and support services to help individuals manage their alcohol use. The model suggests that alcoholism is a chronic, progressive disorder characterised by physical and psychological dependence on alcohol. It affects all aspects of an individual's life, including relationships, work performance, and health.
There is evidence to support the disease model of alcoholism. Studies of animal and human genetic predispositions suggest the presence of genetic influences over drinking behaviour, as well as biological risk factors related to deficiencies in various neurochemicals. Ethanol affects the fluidity of cell membrane lipids, causing membrane dysfunction and adversely impacting the activity of monoamine oxidase and adenylate cyclase enzymes, which are important for the brain's information processing system. Research on condensation products formed in the brain after alcohol consumption has also provided clues to the development of alcoholism.
However, some physicians, scientists, and addiction experts reject the disease theory of alcoholism on logical, empirical, and other grounds. Critics argue that removing stigma and personal responsibility through the disease concept may increase alcoholism and drug abuse, leading to a greater need for treatment. Additionally, the disease model of alcoholism does not align with the standard biomedical model that underpins many medical doctors' training.

Genetic influences contribute to chemical imbalances in the brain
Alcoholism, or alcohol use disorder (AUD), is a complex disorder involving problematic ethanol ingestion. It is influenced by both genetic and environmental factors. Current evidence indicates that alcoholism is 50-60% genetically determined, with the remaining influenced by environmental factors.
Genes are segments of DNA that contain codes for proteins that function as chemical messengers in the body. These chemical messengers, or hormones, have powerful effects on emotions. Abnormal emotional traits in alcoholics, such as emotional dysfunction, may be inherited and are associated with corresponding abnormalities in frontal, limbic, and cerebellar brain systems. For example, alcohol initially reduces negative emotional states by dampening activity in the extended amygdala, which mediates the fight-or-flight stress response. However, excessive alcohol use can lead to tolerance, requiring increased consumption to achieve the same effect. During withdrawal, the amygdala circuits become hyperactive, leading to hyperkatifeia, or heightened negative emotional states.
Research has identified a group of genes that influence neuronal plasticity, pain perception, and brain communication, which are also associated with an increased risk for AUDs. These genes may undergo silent mutations, influencing the rate and conformation of gene transcription and causing changes in other genes that impact alcoholism. The discovery of these genetic influences raises the possibility of genetic testing for alcoholism, allowing individuals with a high genetic tendency to make informed decisions about their alcohol consumption.
Additionally, the plasticity of the human brain contributes to the development of AUD. Alcohol produces chemical imbalances in specific neurocircuits and can be neurotoxic, impacting brain regions involved in motivation, memory, decision-making, impulse control, and other cognitive functions. These brain changes can make it increasingly difficult to stop drinking without assistance.
It is important to note that the disease model of alcoholism is not universally accepted. Some critics argue that it removes stigma and personal responsibility, potentially increasing alcoholism and drug abuse. However, the American Medical Association (AMA) has endorsed the dual classification of alcoholism under both psychiatric and medical sections, recognizing it as an illness.

Environmental factors influence the development of alcoholism
The development of alcoholism is influenced by a multitude of factors, including both internal and external elements. While genetics and personal history play a significant role, environmental factors are also key contributors. The term "environment" in this context refers to community- or societal-level factors such as per capita alcohol consumption, drinking norms, and alcohol availability. It also encompasses social network factors like peer relationships and family circumstances.
One of the critical environmental factors influencing the development of alcoholism is the pervasiveness of alcohol in an individual's surroundings. The more accessible and prevalent alcohol is in a person's environment, the higher the likelihood of them developing alcoholism. This includes factors such as the number of alcohol outlets in an area and the drinking norms within their community or social network. For example, individuals from wealthier families are more likely to consume alcohol heavily and develop alcohol use disorders. This is supported by statistics from the United States, where 78% of individuals with annual household incomes of $75,000 or more drink alcohol, compared to only 45% in households earning less than $30,000.
Family circumstances and peer relationships also play a significant role in the development of alcoholism. Adverse childhood experiences, such as abuse, parental divorce or death, and witnessing violence, have been linked to an increased risk of alcoholism. Additionally, low parental monitoring and associations with deviant or antisocial peers can contribute to higher alcohol consumption among youth. On the other hand, strong family and social networks that discourage alcohol use, such as strict religious beliefs that influence local laws and social practices, can act as a protective factor against alcoholism.
The influence of environmental factors on the development of alcoholism is complex and multifaceted. It involves the interaction of various elements, including community norms, social networks, and individual genetic predispositions. While certain environmental factors can increase the risk of alcoholism, others can provide support and protection against the development of alcohol use disorders. Understanding these environmental influences is crucial for developing effective prevention and intervention strategies to address alcoholism.

Alcoholism is a progressive disease
The modern disease theory of alcoholism states that problem drinking is caused by a disease of the brain, characterized by altered brain structure and function. Alcohol use disorder (AUD) is the scientific term for alcohol dependence and alcohol-related problems. It is considered a brain disorder, and individuals with AUD exhibit impaired control over their alcohol consumption despite adverse consequences. The risk of developing AUD is influenced by genetic and environmental factors, with hereditability accounting for approximately 50-60%. Research has also pointed to the possibility of the existence of a "tolerance gene," which may promote alcohol obsession.
The disease model of alcoholism suggests that alcoholism is a chronic and progressive disorder characterized by physical and psychological dependence on alcohol. It affects all aspects of an individual's life, including relationships, work performance, and health. Individuals with alcohol addiction are likely to experience recurrent relapses unless they seek treatment and support. The model proposes that alcoholism is a complex medical condition influenced by biological and environmental factors, removing the stigma associated with addiction and viewing it as more than just a lack of control or moral failing.
Several treatment approaches are available for AUD, including counseling, behavioral therapies, mutual-support groups, and medications. Treatment is individualized, and a combination of these approaches may be used. The disease model helps reduce the severity of symptoms associated with alcohol dependence and has provided a system for recovery for millions of people struggling with addiction.
While the disease model of alcoholism is widely accepted, it has faced criticism and rejection from some physicians, scientists, and addiction experts. Some argue that it removes personal responsibility and increases alcoholism and drug abuse. Critics also state that alcoholism does not follow the model of a disease and is not amenable to standard medical treatment.

Treatment for alcoholism includes therapy and medication
The modern disease theory of alcoholism states that problem drinking is caused by a disease of the brain, characterised by altered brain structure and function. The largest association of physicians, the American Medical Association (AMA), declared that alcoholism was an illness in 1956.
There are various treatment options for alcoholism, including therapy and medication. Therapy can be conducted in a one-to-one, group, or family setting. Psychotherapy, for example, involves a patient talking to a trained psychologist about their problems and experiences. Dialectical Behaviour Therapy (DBT) is another type of evidence-based talk therapy. DBT involves learning to live in the present instead of dwelling on the past, managing emotions and distress, and practicing honest communication. Cognitive Behavioural Therapy (CBT) is another proven method for treating alcoholism. CBT focuses on identifying negative thoughts and behaviours and replacing them with positive ones. Motivational interviewing (MI) is a popular technique for treating substance abuse disorders. MI involves encouraging a patient to overcome ambivalence, set direct goals for self-improvement, and stay motivated to realise them.
In terms of medication, the U.S. Food and Drug Administration has approved three medications to treat alcohol use disorder: acamprosate, disulfiram, and naltrexone. Acamprosate and naltrexone reduce alcohol consumption and increase abstinence rates, although the effects are modest. Other medications may also be beneficial, such as the anticonvulsants topiramate and gabapentin, which may reduce alcohol ingestion.
Treatment for alcoholism can be expensive, so it is important to evaluate the coverage provided by one's health insurance plan. Some programs may offer lower prices or payment plans for individuals without insurance. It is also important to gauge whether a treatment program offers all currently available, evidence-based methods or relies on one approach. Matching the right therapy to the individual is crucial to the success of the treatment.
There are also free, confidential helplines that individuals can call to receive referrals to local treatment facilities, support groups, and community-based organizations. These include the SAMHSA's National Helpline (1-800-662-HELP) and the Substance Abuse and Mental Health Services Administration's National Helpline (800-662-HELP).
